dunno whats wrong
int n;
cin >> n;
int a[100][100];
for(int i=0;i<n;i++)
{
for(int j=0;j<n;j++) { cin >> a[i][j]; }
}
for(int i=0;i<n;i++)
{
for(int j=0;j<n;j++) { cout << a[i][j]; } cout << endl;
}

If Your value of n is >=101 your code will give RTE.
I hope this will be helpful.
i tried a[n][n] but cant,so i deciced to fix the size
Yes you should try to use a[n][n] but only for a specific upper bound of n this notation is valid.
Not sure but allocation of around [100000][100000] give error in my machine :(
Don't know the accurate upper bound.
of course it gives an error, 100000*100000 integers is about 40000 megabytes
You don't understand what a 2D array memorizes.
If we define a[N][M] , that means you can use a[0~N-1][0~M-1] , and other position will get some wrong value or Runtime Error.
If N,M is too big , you will get Memory Limit Exceeded.
actually,ima give the problem i tried to solve https://codeforces.com/contest/1360/problem/E submission:https://pastebin.com/fN5BxL0e
That's a string , not a number in the 2D array in the problem.
So you shouldn't read a number , but a char.
